I think your IOS is corrupt.  Download it again.

Re: Router booting problem

How big is your CF again?  How big is the IOS you are trying to load?  Upload the IOS that require only 64mb.  Try using TFTPDNLD process as this is alot faster.

Re: Router booting problem

Ok then.  Reload the router and let it go into ROMmon.  On the first prompt type "i" and hit return.  Load the IOS again using TFTPDNLD.  Make sure you load the IOS that requires only 64mb and not the larger one.

Re: Router booting problem

Ok.  Now I'm getting confused.  Your post shows that the router is unable to boot but you are more concerned about the CF upgrade from 64mb to 128mb.  Am I understanding your issue?

If this is your issue, my question is this:  Is the 128mb CF formated by the router?

Re: Router booting problem

Right, this can mean either the following:

1.  There is no CF in the CF slot of your router; or
2.  CF is faulty

Have you tried loading the IOS into the DRAM using the "-r" option?

Re: Router booting problem

Hi Arup,

Kindly leave the 128mb CF out of the picture as of the moment.  The current issue is that your router WILL NOT BOOT.  I would like to solve this issue first before tackling the 128mb issue.

If you say that the 64mb CF works in other routers, kindly insert the 64mb CF into the router and see if it will boot.

Re: Router booting problem

Hi Arup,

You're not making this easy, Arup. 

Right, then.  Take the 128mb CF and insert it into a fully functional router with the IOS fully loaded.  If you have the right CF the "sh log" will reflect that.

Now, if you do see evidences that the 128mb CF is valid by this router, run the command "format flash:".

Once the format is finished (should take a few minutes) copy the IOS from your TFTP server to the CF.  Once it's done, verify using the command "verify /md5 flash:"

Re: Router booting problem

Hi Arup,

That's not what I had in mind.  In the lower left-hand corner of my post there are greyed out stars.  There are two columns or groups.  Over the left column, hover your curser over it.  One star to five star.

Re: Router booting problem

Hey Leo, sorry to interrupt, but if Arup uses the e-mail feature to respond to the thread, he might not be able to see the stars. Anyway, I can see them clearly.

Router booting problem

After much messing around I found the issue

The probability is that the CF card you are using has been used before.

'show flash: all' will tell you if the File System Type is FAT16 or not, of this new CF card you are trying to use

in my case format flash: was formatting the card BUT not as FAT16, it was using the same as it was originally done by the PC. I reformatted my card on the PC (W7) which was giving me this grief as FAT16 and bingo! I now have a 512MB CF card for my CME router

When you are running the usual IOS image, FAT32 CF card is readable, but not from the ROM image at boot time, this MUST be FAT16

Thank you alanwright1 for posting the SOLUTION.

Hello, I had exactly the same

Hello,

 

I had exactly the same issue with some NEW FLASH CARDS.

The work around was to format them with ONLY the BOOT FLAG , by default it was formated using BOOT and LBA.

 

With GPARTED (LINUX) I just removed the LBA flag and I was up and running.

 

PS: I do not use unofficial FLASH CARDS in production , I just use this kind of card in my CCNA LAB.

 

Best Regards,

Didier
